I couldn't find anything - happy to look into it if someone points me to the ticket. Cheers, Simon On 20/09/2009 12:22, Lennart Augustsson wrote:

I complained about the very same thing, I think there's even a ghc bug report about it. It's something about how symbols are looked up and loaded in ghci. I've not been able to come up with a workaround either.

The package statistics uses the package erf. Doing cabal install statistics works fine but when I try to use anything I get:

...

I assume that erf is looking for some C functions which are available on linux but not windows.

I'm not sure what the solution is. Should cabal complain? Should there be some documentation on the erf homepage telling windows users what to do? Or at least that it doesn't work on windows?
